Very slow Httpurlconnection implementation when running

Question

I’m using the class HttpURLConnection to make the connection to a site that returns a JSON and I did the following encoding:

URL url = new URL("http://hmkcode.appspot.com/rest/controller/get.json");

HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.connect();

When executing the methods url.openConnection() and connection.connect() the system takes a long time to respond. I even have the desired feedback, but it takes about 5 minutes to execute the methods. Why is this happening? Remembering that I am doing everything within the method doInBackground of a AsyncTask
